Databinding in XBAP throws reflection error

Question

I have a listbox that I'm binding to a collection of objects.

In the code behind, I get a list of the jobs and bind it to the listbox items source:

List<JobEntity> jobList = new List<JobEntity>();
Job j = new Job();
jobList = j.LoadJobs(pageSize, pageIndex);
lbxJobs.ItemsSource = jobList;

In the xaml, I then try and access some of the properties of the job.

   <ListBox.ItemTemplate>
        <DataTemplate>
         <WrapPanel>
          <TextBlock Text="{Binding Path=Title}" Margin="5 0" />
          <TextBlock Text="{Binding Path=HiringCompany}" Margin="5 0" />
         </WrapPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>

This works fine for a normal wpf application, but as an xbap app it throws an error that basically says it can't get the value because Reflection Permissions were denied.

System.Windows.Data Error: 16 : Cannot get 'HiringCompany' value (type 'String') from '' (type 'JobEntity'). BindingExpression:Path=HiringCompany; DataItem='JobEntity' (HashCode=64844482); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String') TargetInvocationException:'System.Reflection.TargetInvocationException: Property accessor 'HiringCompany' on object 'JobSearch.Classes.JobEntity' threw the following exception:'JobSearch.Classes.JobEntity.get_HiringCompany()' ---> System.MethodAccessException: JobSearch.Classes.JobEntity.get_HiringCompany() ---> System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed

Has any one run into this before or found a workaround for this error?

Answer 1

I just found the answer to my own question. I didn't have my JobEntity class explicitly declared as "public". Doing that resolved the issue.
